I have five people in meatspace who know my Hubski identity. Dala and PlaceboEffect are two of them, the other three don't have Hubski accounts but are discreet, trustworthy, and understand the significance of a pseudonym.

I'd be more than happy to share this site with others, but I think I'd do so without letting them know my screen name, though I'd doubt it'd take long to figure out who I am.

Not really a constructive response here, just my situation and maybe some food for thought.

I hear that. I have so many people in my life that I know would love Hubski, but it's a hard sell. It's something you have to participate in or visit regularly before you really start to get it. Much of the site is knowing the personalities, IMO. If you visit a dive bar once, you might think it's just four walls and some liquor but once you visit a number of times you realize the people that inhabit it are what make it unique. It takes time.
